Ozzy Osbourne's attorneys have threatened to take legal action over a brand of ale which shares its name with the rock star.

The Black Sabbath frontman's legal team has sent a cease and desist letter to bosses of The Brewer's Art, a brewery based in Baltimore, Maryland, over an ale called Ozzy.

The brand's artwork features the name inked on the fingers of a clenched fist, similar to the tattoo the rocker sports on his knuckles, along with a bat logo, seemingly in reference to Osbourne's infamous stage stunt in which he bit the head off a live bat.

Tom Creegan, owner of The Brewer's Art, confirmed the legal dispute to The Baltimore Sun newspaper, revealing he had received a letter from Osbourne's attorneys.
